RESUMEN
INTRODUCTION: 10-16% of non-small cell lung cancer (NSCLC) cases have the epidermal growth factor receptor (EGFR) amplified and/or mutated. Studies show that EGFR tyrosine kinase inhibitors (TKIs) significantly prolong progression-free survival (PFS) in patients with advanced NSCLC compared to those treated with platinum-based chemotherapy (CT) doublets. Our aim is to perform a real-world survival analysis of patients treated with TKI as first-line therapy at the Hospital of Leon (CAULE) in Spain. The impact on global survival rates and responses to clinical and histopathological factors were also analyzed. MATERIAL AND METHODS: We retrospectively reviewed patients diagnosed with EGFR-mutated NSCLC who received treatment with EGFR-TKI in the Department of Oncology at the University of Leon Health Center complex between March 2011 and June 2018. Data was analyzed with Kaplan-Meier and Cox regression models to show overall survival (OS), progression-free survival (PFS), and the associated variables. RESULTS: 53 patients were included in the study, 50% (n = 27) were treated with gefitinib, 32% (n = 18) with erlotinib and 10% (n = 6) with afatinib. The median OS and PFS were 27.7 months (95% CI: 21-33.8 months) and 18 months (95% CI 14.25-21.89 months), respectively. The variables associated with OS and with PFS were exon19 deletion as a protective factor and presence of extrathoracic metastasis as a risk factor. The most frequent adverse effects were rash, diarrhea, asthenia, and conjunctivitis. CONCLUSIONS: Real-world analysis of this data confirms that treatment with TKI is beneficial for patients diagnosed with EGFR-mutated NSCLC. Our OS outcomes were similar to those reported in clinical trials.

El carcinoma nasofaríngeo es el tumor más frecuente que surge en la nasofaringe. Su etología es multifactorial, considerándose como factores de riesgo la distribución racial y geográfica, la infección por el virus de Epstein-Barr (VEB), así como la exposición ambiental a determinas sustancias. Esta afección es endémica en algunas zonas asiáticas, donde se han encontrado predisposición genética en su oncogénesis. Existe una fuerte susceptibilidad entre el carcinoma de nasofaríngeo y el HLA, donde se han encontrado haplotipos relacionados específicos. En zonas donde la incidencia es baja, existen pocos casos publicados sobre familias afectadas. Reportamos 3 casos de familias con carcinoma de nasofaringe entre hermanos, en población no asiática, probablemente relacionada con la infección por el VEB (AU)
Nasopharyngeal carcinoma is the predominant tumour type arising in the nasopharynx. Its aetiology is multifactorial; racial and geographical distribution, EBV infection and environmental exposure to specific substances are considered risk factors. This condition is endemic in some Asian areas, where a genetic predisposition in its oncogenesis has been established. There is a strong susceptibility between nasopharyngeal carcinoma and HLA, where related specific haplotypes have been found. In areas where the incidence is low, there are few reported cases of families affected. We report 3 cases of families with nasopharyngeal carcinoma among siblings, in the non-Asian population, probably related to EBV infection (AU)
